Virtual Earth 3 Installation Bug Fixed for International Users
I've attached a screenshot of downtown San Francisco in 3D with Coit Tower in the foregroud. In playing around with Virtual Earth 3D (beta) I was a little disappointed with the download/rendering speed, also in panning around and viewing San Francisco from several angles, it only brought up the Transamerica Pyramid once -- it is noticeably absent in the attached screenshot. Anyway, it is bound to get a lot better, this is only a beta after all.
